INPUTS AND OUTPUTS
All analog inputs of this system consist of temperature
measurements made by NTC sensors.

pCO Analog Inputs (Mother Unit)
Table 6.

pCO Digital Outputs (Mother Unit)
The configuration of the inputs and outputs depends on the initial
configuration of the system.
The tables in this section show the inputs and outputs assigned to
each type of configuration as well as the port used for the “Mother”
unit (whose capacity is regulated by a drive or an unloader) and
the “Child” units.
Key: CO is for Cooling only and HP is for Heat Pump.

Note: Digital motor protector inputs on “Sons” units are
optional and their consideration depends on the
initial configuration of the system, on the other
hand motor protection input on “Mother” units is
indispensable.

Note: The digital output pump in “Child” units depends on
the initial system configuration. It is not possible
to use it if the system is configured with only one
“Mother” pump (pCO unit).
START-UP
24 V
• Place the Control switch in the ON position
to activate the 24 VAC control.
• After the control is turned on, it will take 2
minutes for the unit to come Online.
Compressor
• Place the switch in the ON position (Fig.2),
this allows the compressor to turn on and
off according to the status.
Note: Once the pump is turned on, it will take a few seconds
until a uniform flow of water is detected, at the end
of this delay, the flow switch will be monitored. If the
switch is on it commands the pump to turn off (5
attempts within 10 seconds). If a uniform water flow
is detected the unit will begin operation.
• Under normal conditions, the equipment will turn on and off
the unit’s cooling circuit, according to its needs. When alarms
are present in the system, they will always be indicated on the
user interface.
• The digital control will start compressor operation according to
the logic set in the control.
